"We must risk it," declared the Sub. "It's touch and go." Boldly leaving their place of concealment and descending the slope, the two fugitives approached the Turkish soldier. The man, knowing nothing of what was taking place at the seaward end of the valley, stiffly saluted the supposed German officers, and when they clambered awkwardly into the saddles he offered no objection, although his face showed unbounded surprise as he was left with only one horse in his charge. Obediently the captured steeds broke into a canter. Perhaps it was well that they did not gallop, for both officers were indifferent horsemen. Like most seamen they could hold on to practically anything, so they stuck to the saddles and resisted the involuntary inclination to be pitched off into the dusty road. "Now for it," muttered Dick, as a sharp bend in the mountain path brought them in sight of the mounted rear-guard. It was an anxious thirty seconds, but before the Turkish irregulars could penetrate the deception the two British officers were through and heading towards the open country. [Illustration: "BEFORE THE TURKISH IRREGULARS COULD PENETRATE THE DECEPTION THE TWO BRITISH OFFICERS WERE THROUGH"] "Enough!" gasped Dick after cantering another two miles. "We'll abandon the gee-gees and trust to our legs. We wouldn't stand a ghost of a chance when those fellows are ordered in pursuit." Almost pulling their steeds upon their haunches they dismounted, and reluctantly administering a sharp cut with the flat of their scabbards upon the animals that had served them so well, sent them galloping madly in the opposite direction to that of the convoy. Then, taking a course almost at right angles to the road, the fugitives were soon deep in a scrub-covered expanse of undulating ground. "A good start," ejaculated Dick breathlessly. "By the time they've discovered their mistake over those two German officers and have explained matters to the Turks, we ought to be well on our way to Kum Kale." "Twenty-four hours, they said, before the submarine puts to sea, sir," remarked Farnworth. "We ought to do it well before that time." "I hope so," added the Sub. "By Jove! It will be a serious matter if we don't." Once more night was drawing on apace, yet, in their ardour to warn their comrades of an unexpected peril, they gave no thought to fatigue. Guided by the stars, the Sub shaped a course which he reckoned would bring them within the district supposed to be held by the French Expeditionary Force. By daylight they should be well within sight of Kum Kale. "Steady!" cautioned Dick, as they commenced to descend a steep declivity. "I fancy we're close to the sea again." "I certainly can hear surf," declared the midshipman. "So much the better unless the coast is very much indented," added the Sub. "We can't be so very far from Yenikeui." "Hope the Turks aren't there in force, like they were last time, sir."
